In PSE9, often (about 50% of the time) when I edit a photo, the new version is not added to the catalog. I have to locate the edited version through Files & Folders, adding it manually to the organizer.

Was the original photo in your Organizer? If it was not, then the edited version will also not be in the Organizer, unless it was saved to the Organizer.

When I first started using PSE, I occasionally would open up a photo file that was not in the Organizer, do an edit on it (in PSE) and then close the file. Later on I would re-open PSE and not be able to see the edited photo in the Organizer.

So, make sure the original photo is already in the Organizer before doing any editing. When you saved the edited file, did you check the box that says to "Include In Organizer"?

Thanks for tryingbut nope, it's on the main hard drive, and the directory to which it's saving is the same one in which the original photo appears. All my photos are in subdirectories (by date) of the main Photos file folder. And in fact, the edited photos DO end up in that spotthey are being created properly, just not added to the Organizer and version set.
